Hy4 preview Is Now Available on WorkBuddy for Work and Coding Tasks
Tencent’s 770B open-weight Hy4 preview is now selectable inside WorkBuddy, the company’s desktop AI agent for office and coding work, and it is free there until 10 September 2026. This piece covers what the integration changes for daily work, how the model switch works and what it is recommended for, the 163-expert blind test that Tencent ran inside WorkBuddy against GLM 5.3 and Kimi K3, the benchmarks that matter for work and coding tasks, the quota and reasoning-time caveats, the API and local GGUF routes for teams that would rather not use the app, and how WorkBuddy compares with Claude Cowork.
